What is the problem if the interior light stays on all the time?

[MadelynDella]

The interior light stays on all the time because it is set to the always-on mode. In this mode, the interior light will turn on as soon as the car is powered. To solve this issue, simply switch to the always-off mode or the door-activated mode. Below are details about the interior dome light: Modes of the interior dome light: There is usually a button next to the interior dome light with three modes: ON (always-on mode), DOOR (light turns on when the door is opened and off when closed), and OFF (off mode). When set to DOOR, the light will automatically turn on when the door is opened and off when the door is closed. Switch for the interior dome light: Most interior dome lights not only have a mode selection switch but also a separate on/off switch. Some car interior lights can be pressed to turn on or off, a feature many car owners are unaware of. You can try pressing your car's interior light to see if it has this function.
